摘要： PROBLEM TO BE SOLVED: To extend a weft in a prescribed period between the end of picking and the time of beating up by a conventional tractive force corresponding to the kind of a yarn by using a sub-nozzle in an air-jet loom. SOLUTION: Each solenoid valve 19 is opened according to every pulse by outputting a pulse series of driving signals to the solenoid valve 19 of either one sub-nozzle 11 in an extending period from the end of picking till the time of beating up in a picking device 1 of an air-jet loom. A pressurized air 13 having a different pressure from a pressurized air 12 for the picking is supplied to the sub-nozzles 11 and the pressurized air 13 from the opened sub-nozzle 11 is jetted as an extending air for the yarn.

摘要： PROBLEM TO BE SOLVED: To realize the control of a weft yarn arrival time with quick responsiveness within a wide control range. SOLUTION: A feeding passage of pressurized air to a picking nozzle 13 is composed of a parallel passages for feeding pressurized air under a low pressure and that under a high pressure in an air jet loom capable of feeding the pressurized air to the picking nozzle 13, then jetting the pressurized air from the picking nozzle 13 and thereby inserting a weft yarn 2 together with the jetted air into a warp yarn shedding 16. The deviation Δθe of the weft yarn arrival time Se from the standard weft yarn arrival time for the picked weft yarn 2 is sensed during the picking operation. The high-pressure air jetting period and the picking starting time are changed on the basis of the deviation Δθe.

摘要： PURPOSE: To provide a method for checking the reeding position of a warp, capable of surely and easily checking the reeding position in the precision of an ordinal detector, when plural warps are reeded between the dents of a reed. CONSTITUTION: This method for checking whether the reeding position of a warp 1 is right or not, when plural warps 1 are reeded between the dents of a reed 2, comprises driving only a heald frame 4 in the stopped state of a loom to move only the heald frame 4 from other among the plural heald frames corresponding to plural warps 1 reeded between the common dents, thus changing only one warp 1 from the others among the plural warps reeded between the dents, detecting the presence or absence of the warp 1 moved from the other warps with the detector 15, and subsequently comparing the detected data with regular data to check whether the reeding position of the warp 2 through the reed is right or not.

摘要： PURPOSE:To enable control of the stitch density to a constant value and to enable reproduction of the optimum touch by detecting the amount of a fed yarn corresponding to the tension of the fed yarn and controlling the tension of the fed yarn in a flat knitting machine. CONSTITUTION:In a knitting machine in which the tension of a fed yarn is controlled corresponding to a calculated deviation value between the target yarn length and the actually consumed yarn length, the optimally set tension value and the corresponding standard yarn length shown in case the tension is set in a trial knitting so as to optimize the stitch density and the touch of an actual knitted fabric corresponding to a knitting pattern are memorized. In an actual knitting, the set tension and the target yarn length are changed respectively to the optimum tension value and the optimum standard yarn length corresponding to a knitting pattern in that knitting.

摘要： PURPOSE:To provide a picking system designed to improve its service life and operability by using an electromagnetic pump in place of a mechanical pump to set the water pressure or water jet period necessary for weft carriage through electric operation via a pump controller. CONSTITUTION:In a water jet loom, the objective picking system is so designed that an on-off control valve 12 to be left opened from picking initiation to termination is equipped at a water feed channel situated between a picking nozzle 6 and an electromagnetic pump 11 made up of an electromagnet generating a magnetic field rectangularly to the electrically conductive stream in an electrical insulating tube and a pair of electrodes applying current rectangularly to both the stream and the magnetic field, and a pump controller 14 to feed current to the electromagnetic pump 11 throughout picking period is also equipped. This pump controller 14 into which the rotational angles of the main shaft 16 have been inputted from an encoder 17 compares and stores such angles throughout picking, and over this period, applies specified current to the electromagnetic pump 11 via a switching means and supplies water necessary for weft carriage to the picking nozzle 6.

摘要： PURPOSE:To suppress fluctuation in the traveling speed of carrier by increasing the arranging interval of linear motor. CONSTITUTION:Linear motors 12 are arranged along a guide rail 11 and secondary conductors 14 to be mounted on a carrier are coupled mechanically such that the overall length L thereof is longer than the length L2 of the linear motor 12. Since the secondary conductors 14 produce driving force while opposing to the linear motors 12, powering section of carrier can be distributed appropriately within an arranging interval D.
